SPECIFICATION `forming pant` of Letters Patent No. 278,306, dated May 2,1883.

Application led March 23, 1883., (No model.)

hBe` it known that I, JASPER BATES, of Thornbury, in the county' ofGrey, in the Province of Ontario, in the Dominion of Ganada, haveinvented certain new and useful Im` provements inMa-nual Powers; and Ido herebydeclare that thefollowing isa full, clear, andexact descriptionof the same.

This in vention consists of a machine in which acompound I ever isworkedby the hands, feet, and seat of the operator for driving machinery havingeither a reciprocating or a rotary inotion.

Figure lis a perspective view of my improved machine; and Fig. 2 is avertical section o f the same, showing its motion in dotted t lines.`

A is `the base-plank, raised from the ground upontransverse feet B,which support the machine in a standing position.

C C are parallel vertical posts, footed tothe base A, and connected attop by cap l), hav` y ing a central hole, through which passes the stem.E of a seat, li, on which the operator sits. The lower end of stem Ebears upon one end of a horizontal lever, G, fulcrumed be tween postsHH, secured to base A. l `The opposite end ot' the lever G connects,pivotally, with the end ot'a horizontal lieg of an elbowlever, I, whichis fulcrumed at: its angle to posts J J, secured to base A. In a slot inthe upperend of the vertical leg ot' lever I is pivoted the shaftot' ahandle, K, extending toward the seat F. The pin connecting levers G Iprojects ou opposite sides of the levers and carries footrests Lr Thepin works in an y elongated hole in one of the levers,whereby bothlevers willhave play motion at the point of connection to tilt above andbelow a hori-V zontal position, `as seen in Fig. 2. y

Ois a brace to strengthen the angle or elbow of lever I; and P is apitman pivoted to lever I, to connect horizontally with the mechanism tobe driven.'` Q is a removable bar, at tached to horizontal arm of leverI lby thumbscrewN, to obtain a long vertically-operating stroke, ifrequired; or theattachment of the mechanism to be driven may be to anymoving part ot my machineand in any suitable manner. 1

When the operator depresses the seat the connected ends of levers G Irise and pivotally throw forward the vertical arm, to which the pitmanis connected, and when the operator transfers his weight onto his feet,placed on rests L, the depression thereby ot' the connected ends of thelevers will rais-e the sea-t and recede the vertical arm, thusperforming hand in the presence of thetwo undersigned witnesses. h
